Trademark classes are more than filing categories. In a U.S. trademark application, they help the United States Patent and Trademark Office organize goods and services, calculate filing fees, and make the register easier to search. Choosing the right class is therefore a procedural step that can affect how smoothly an application moves forward. The class number, however, does not replace a clear description of what you actually sell or provide.
The United States uses the international Nice Classification system. Under the current Thirteenth Edition, version 2026, goods fall in Classes 1 through 34 and services in Classes 35 through 45, giving applicants 45 international classes in total. Applicants still must identify their goods or services with enough specificity to meet USPTO requirements.
How trademark classification works
A trademark application does not protect a word, logo, or other mark in the abstract. It identifies the goods or services with which the mark is used, or will be used, and places those items into one or more international classes. Trademark classification gives the USPTO a standardized way to group related commercial activity.
For example, Class 25 generally covers clothing, while Class 41 covers education and entertainment services. A business selling branded T-shirts may file in Class 25. If the same business also offers online fitness instruction under the same mark, those services may require Class 41. Both classes can appear in one application, but each class has its own filing fee and requirements.
Goods and services use different class ranges
Classes 1 through 34 cover goods, while Classes 35 through 45 cover services. The broad headings are useful orientation tools, but they are not enough to classify every item accurately. The USPTO advises applicants to use its Trademark ID Manual to find acceptable wording and the proper class for specific goods and services.
Why the identification matters as much as the class
A common mistake is assuming that selecting the correct class automatically defines the scope of a registration. It does not. The class number is mainly an administrative classification. The identification of goods or services tells the USPTO what the applicant is actually claiming.
Suppose a company sells downloadable budgeting software. Simply choosing a technology-related class is not the end of the task. The application should describe the software accurately enough to show what it is and, where required, what it does. Clear wording helps the examiner understand the commercial activity and determine whether the classification is correct.
This is also why copying a broad heading from the Nice Classification can be risky. The Nice system is designed to classify goods and services internationally, while the USPTO applies its own standards for acceptable identifications in U.S. applications. For most applicants, the Trademark ID Manual is a better starting point than a class heading alone.
How trademark classes affect filing fees
USPTO application fees are calculated per international class. As of 2026, the base application filing fee is $350 for each class when the application meets the requirements for the base fee. Additional fees can apply in some situations, including certain customized descriptions of goods or services.
If all of an applicant’s goods fall within one class, only one class fee may be needed. If the business needs coverage for goods or services across three relevant classes, the application generally requires a filing fee for each class. Applicants should not force unrelated items into fewer classes simply to reduce cost; inaccurate classification can create examination problems.
Different classes do not automatically prevent conflicts
Two marks do not automatically avoid a conflict just because their applications list different USPTO classes. Trademark conflict analysis looks at the similarity of the marks and whether the goods or services are related in a way that could make consumers believe they come from the same source.
For that reason, a useful search should not stop at the exact class you expect to file in. Related goods and services may appear in other classes. A broader review can uncover conflicts that a class-only search could miss. A trademark search guide is a natural next step for applicants who want to understand that process before filing.
A practical way to choose the correct class
Start with the product or service you actually offer, not with the class list. Write a plain-English description, then search the USPTO Trademark ID Manual for matching or closely related entries. Check the assigned class and confirm that the wording accurately reflects the real activity.
Software is a useful example. Downloadable software and online non-downloadable software can be classified differently depending on how the product or service is delivered. The difference may seem minor from a marketing perspective, but it can matter in trademark classification. Describe the actual offering rather than relying on a broad label such as “technology.”
If one mark will cover several products or services, a trademark application process guide can help explain multiple-class filings. Trademark protection basics can also provide useful context for how identification, use, and likelihood of confusion fit together.
What happens in a multiple-class application?
A multiple-class application covers goods or services in more than one international class. Each class must satisfy the applicable filing requirements, and fees are calculated by class. Depending on the filing basis and stage of the application, proof of use and other requirements may also need to be addressed separately for each class.
This structure lets a business cover several lines of activity in one application. Careful drafting still matters because an issue in one class can require attention even when other classes are acceptable.
FAQ about trademark classes
How many trademark classes are there in the United States?
The USPTO uses 45 international classes under the Nice Classification. Classes 1 through 34 cover goods, while Classes 35 through 45 cover services.
Can one trademark application include more than one class?
Yes. A U.S. application can include multiple international classes when the mark covers goods or services in different classes. Filing fees are generally charged for each class.
Does choosing a broader class give broader trademark rights?
No. A class number is an organizational tool and does not by itself expand trademark rights. The identified goods or services, actual use, and the legal relationship between the parties’ goods or services matter more to the practical scope of protection.
Where should I check the correct class before filing?
The USPTO Trademark ID Manual is the best starting point for U.S. applicants because it includes pre-approved descriptions and their classifications. The Nice Classification provides broader international context, but USPTO identification standards still apply.
Choosing classes with filing strategy in mind
Trademark classes make the filing system manageable, but the real task is matching a business’s actual goods and services to accurate, acceptable descriptions. Use the class number as a framework rather than a shortcut. A well-prepared application identifies what the business truly offers, assigns each item to the proper class, and anticipates the fees and examination requirements that follow.
For U.S. applicants, start with the goods or services, verify the wording against current USPTO guidance, and let the classification follow from the real commercial activity.
